Resumen
Byproducts from the winery industry contain many bioactive compounds that are considered high-value-added compounds. White grape pomace (GP) is rich in carbohydrates, consequently, it can be used as a raw material for subsequent bioprocesses. In the present study, low-temperature hydrothermal treatments were carried out using different operational conditions regarding temperature (65-95 & DEG,C), time (120-240 min), and sulfuric acid addition at various concentrations (5-15% v/v). The results showed that by using a temperature of 65 & DEG,C, a period of 120 min, and 15% (v/v) of H2SO4, it was possible to obtain a liquid phase rich in phenols and carbohydrates, with total phenol compounds corresponding to 2113 & PLUSMN, 140 mg of gallic acid/kg GP and composed mainly of 3-hydroxytyrosol (1330 & PLUSMN, 22 mg/kg GP). In parallel, carbohydrate solubilization reached 245 g glucose/kg GP. These results demonstrate the promising potential of hydrothermally treated grape pomace as raw material for biorefinery processes.
